Golden Liberty (Latin: Aurea Libertas; Polish: Złota Wolność, Lithuanian: Auksinė laisvė), sometimes referred to as Golden Freedoms, Nobles' Democracy or Nobles' Commonwealth (Polish: Rzeczpospolita Szlachecka or Złota wolność szlachecka, Latin: aureă lībertās) was a unique political system in the Kingdom of Poland and, after the Union of Lublin (1569), in the Polish–Lithuanian Commonwealth. Under that system, all nobles (szlachta), regardless of rank or economic status, were considered to have equal legal status and enjoyed extensive legal rights and privileges. The nobility controlled the legislature (the Sejm — the Polish parliament) and the Commonwealth's elected king.
This political system, unique in Europe, stemmed from the consolidation of power by the szlachta (noble class) over other social classes and over the monarchical political system. In time, the szlachta accumulated enough privileges (established by the Nihil novi Act (1505), King Henry's Articles (1573), and various Pacta conventa) that no monarch could hope to break the szlachta's grip on power.
